  • FIG. 1 depicts a schematic of an electrical connection system 100. The system 100 includes an electrical connection device 102 and a mating electrical connection device 104. In one embodiment, the electrical connection device 102 and the mating electrical connection device 104 can align and engage to each other at contact ends. The electrical connection device 102 may comprise a first contact end 118 and a second contact end 116.

Thus in order to initiate electrical conduction, the first contact end 118 can engage the first mating contact end 128, the second contact end 116 can engage the second mating contact end 126.
  • First contact end 118 and second contact end 116 can be in the form of pins. First mating contact end 128 and second mating contact end 126 can be in the form of sockets.
  • As depicted in FIG. 1, the electrical connection device may further comprise a housing 106 and a conduction engagement device 112. In an embodiment, the housing 106 may be made of a polymer material. In another embodiment the housing 106 may be a metallic composition where the metallic composition may be coated with a polymer to reduce potential electrical conduction and radiant heat generated through electrical conduction. In another embodiment, the housing 106 may be configured to be a unitary piece formed around internal components. In a further embodiment, the housing 106 may be configured from a plurality of pieces that can be configured to lock together during use. In addition, the embodiment with the multi-piece housing 106 may also be configured to separate and provide access to components encompassed by the housing 106.
  • As depicted in FIG. 1, the housing may encompass and protect multiple components, including: the first contact end 118, the second contact end 116, a first connector 110, a second connector 108, and an electrical disconnection switch 120. In one aspect of the disclosure, the second contact end 116 may be connected to the second connector 108. Further, the electrical disconnection switch 120 may be placed between the first contact end 118 and the first connector 110. In another embodiment, the second connector 108 may be a ground connector and the first connector 110 may be a live current connector.
  • As discussed earlier regarding the embodiment in FIG. 1, the electrical disconnection switch 120 may be placed between and connected to the first contact end 118 and the first connector 110. In an aspect of the disclosure, the electrical disconnection switch 120 comprises an enclosure 200 where the enclosure encompasses a first electrical terminal member 122 and a second terminal member 124. In an example, the first and second electrical terminal members are comprised of an electricity conducting material. Accordingly, when the first electrical terminal member 122 and the second electrical terminal member are in physical contact, electrical current can flow through the electrical connection device 102 to the mating electrical connection device 104 and vice versa depending on the direction of electrical current flow. An additional embodiment of the electrical disconnection switch is discussed in FIG. 2.

In an alternate embodiment, the conduction engagement device 112 may be tethered to the housing 106. In the tethering example, a tether may be used to connect the housing 106 and the conduction engagement device 112. The tethered connection will be the only restriction in the range of motion for the conduction engagement device, and the engagement device motion will not be restricted to move along an axis of the housing 106.

  • Regarding material composition, the engagement device 112 may be comprised of a rigid polymer. In another embodiment, the conduction engagement device 112 may comprise a movable magnet instead of a magnet 114 being encompassed in a conduction engagement device composed of a different material. In this example, the electrical terminal members 122, 124 in the electrical disconnection switch 120 may be configured to physically connect when encompassed by a magnetic field.
  • In another aspect of the disclosure, the conduction engagement device 112 may also comprise a locking mechanism. A function of the locking mechanism seeks to ensure that that the magnet 114 stays in proximity to the electrical disconnection switch 112 in order to maintain an electrical connection between the first electrical terminal member 122 and the second electrical terminal member 124. In one embodiment, the locking mechanism of the conduction engagement device may comprise grooves in the inner surface in the conduction engagement device 112 that respectively mate with a grooved surface on the exterior surface of the housing 106. Thus, the mated grooved surfaces may allow the conduction engagement device 112 to be screwed on to the housing 106 at the appropriate region, reducing potential slippage of the conduction engagement device 112 on the housing 106. In another embodiment, the conduction engagement device 112 may have a latch that sets in a notch on the housing 106. In such an embodiment, the location of the notch and latch locking mechanism may be configured to properly align the magnet 114 with the first electrical terminal member 122 and second terminal member 124.
  • The locking mechanism may also hold the electrical connection device 102 to the mating electrical connection device 104.
  • FIG. 2 depicts a schematic of the electrical disconnection switch 120, as discussed earlier. In an embodiment, the electrical disconnection switch 120 comprises an enclosure 200 where the enclosure encompasses a first electrical terminal member 122 and a second terminal member 124. In an example embodiment, electrical current flows in the electrical connection device to the mating electrical connection device when the first electrical terminal member 122 and the second electrical terminal member 124 are in physical contact. In another embodiment the enclosure is sealed to enclose an inert gas 204 to further reduce the likelihood of unintentional electrical current flow. A physical property of the inert gas 204 indicates that there are no free electrons in the gas atoms. This property of the inert gas 204 reduces the possibility of electrical current arcing through a gap between the first electrical terminal member 122 and the second electrical terminal member 124.
  • As discussed earlier, when the conduction engagement device 112 is in proximity to the electrical disconnection switch 120, the magnet 114 in the conduction engagement device 112 causes the first electrical terminal member 122 and the second electrical terminal member 124 to come in contact. In one embodiment, the magnetic force may cause the first electrical terminal member 122 and the second electrical terminal member 124 to rotate about a base end 206. Both terminal members have a base end 206 that may be restricted by the edges of the enclosure 200. In addition, the first electrical terminal member 122 and the second electrical terminal member 124 have a free end 208. When there is no electrical current flowing, the electrical disconnection switch is disengaged. In the disengaged state, the first electrical terminal member 122 and the second electrical terminal member 124 may be structurally configured so that the free ends 208 are set at a predetermined non-engagement displacement 202. In another embodiment, the spring constant of the second electrical terminal member 124 may be higher than the spring constant of the first electrical terminal member 122. A higher spring constant of the second electrical terminal member 124 increases the stiffness of the second electrical terminal member 124. Thus, the movement of the free end 208 of the first electrical terminal member 122 from the initial displacement 202 may be greater when subjected to the magnetic force of the magnet 114. Varying the stiffness between the two electrical terminal members may ensure that the non-engagement displacement 202 will decrease and result in contact of both free ends 208, when the electrical disconnection device 120 is placed in a magnetic field. Accordingly, depending on the placement of the magnet 114, another configuration may use a first electrical terminal member 122 with a higher spring constant than the second electrical terminal member 124.
  • The schematics in FIGS. 3A-3C depict steps in a process of conducting electricity between the electrical connection device 102 and the mating electrical connection device 104. FIG. 3A depicts a mating step. During the mating step, the first contact end 118 and the second contact end 116 are aligned with the respective first mating contact end 128 and the second mating contact end 126. The mating step may be completed when the first contact end 118 is connected to the first mating contact end 128 and second contact end 116 is connected to the second mating contact end 126.
  • FIG. 3B depicts an engaging step. In an embodiment, the engaging step may comprise moving the conduction engagement device 112 in proximity to the electrical disconnection switch 120. In another embodiment, moving the conduction engagement device 112 may comprise translating the conduction engagement device 112 along an axis of the housing 106. Depending on the configuration of the housing 106, alternate forms of motion may be used move the conduction engagement device 112 relative to the housing 106. The alternate forms of motion may comprise twisting, rotating or tethering. The engagement step may be completed when the conduction engagement device 112 is moved to a location on the housing 106 where the magnet 114 is configured to exert a magnetic force on the first electrical terminal member 122 and the second terminal member 124 of the electrical disconnection switch 120.
  • FIG. 3C depicts the power connection step. At the conclusion of the engaging step depicted in FIG. 3B, the magnet 114 causes the electrical terminal members to physically contact. Thus, in the power connection step, there may no longer be a shorted connection in the electrical disconnection switch 120. Accordingly, electricity is permitted to flow through the system 100. In another embodiment, power connection may also comprise locking the conduction engagement device 112 to the housing 106. The mechanism to lock the conduction engagement device 112 on the housing 106 may be used to ensure that the conduction engagement device 112 does not move the magnet 114 away from the location necessary for the magnet 114 to force the electrical terminal members to remain in physical contact.
  • The electrical connection device 102 can be included in an electrical only cable or other electrical only connection. In one embodiment, the electrical connection device 102 is in the form of a plug, and the mating electrical connection device 104 is in the form of a socket or a receptacle.
  • Device 102 can be part of high-voltage hybrid optical/electrical connectivity solution when both power and fiber signals are provided by the same cable. The device 102 could also be used as an interlock to power off a laser source as well, limiting optical reflections or unsafe optical power when disconnected.
  • While there have been described herein what are to be considered exemplary and preferred embodiments of the present technology, other modifications of the technology will become apparent to those skilled in the art from the teachings herein. The particular methods of manufacture and geometries disclosed herein are exemplary in nature and are not to be considered limiting. It is therefore desired to be secured in the appended claims all such modifications as fall within the spirit and scope of the technology.
